COMBINATION HANDLE AND LATCH.

Specification of Letters Patent.

llatented Apr. 22, 1913.

To all whom it m (ry concern.

' Be it known that I, JAY B. Srooxnn, a citizen of the United States,residing at- Santa Monica, in the county of Los Angcles and State ofCalifornia, have invented new and useful Improvements in CombinationHandles and Latches, of which the following is a specification.

This invention relates to combination handles and latches for looks orthe like, such as are used in or on doors or the like, particularly ofthat class or description wherein the usual knob provided thereon iseliminated, and a handle with a latch is provided with which to operatethe latch bolt of the lock.

in eliminating the knob with which the latch-bolt is usually operated,and in order to produce an eifeetive and economical handle insubstitution for the knob, it is especially found desirable to providethe handle with a latch operatively mounted therein.

One of the chief difliculties in providing a combination handle andlatch of the character stated, in which it is more particularly desiredto 0 erate the latch, and move the door or the ike, at one and the sametime, by grasping the handle in the usual manner, and pulling or pushingthe door or the like in the normal way, is to provide the latchoperating means so that the same is inter changeable and subject to use1n locks of various difierent sizes, in different doors.

.An object of the invention is to provide a latch-lever operating latch,neatly and compactly embodied within the door handle or the like, whichcan be quickly and conveniently detached from the lock of a certain sizein one door, and operatively connected to a lock of relatively larger orsmaller size in another door.

Another object of the invention is to provide a latch mounted in ahandle so'thata comparative small hand is capable of operating thelatch, for instance, ladies or very small children, can operatethe latchby simply using one hand with which to pull or push the door or thellke, by grasping hold of the handle in the usual manner.

With the above and other objects in view, in additiOn to which may beadded relative simplicity, and inexpensiveness of construction, andorganization, and positiven'ess' and efficiency inoperation, theinvention consists of the novel provision, construction, and

relative arrangements of parts, and combination of parts, members, andfeatures, all as hereinafter described, shown in the drawings, andfinally pointed out in the claims.

The accompanying drawings are illustrative of the invention.

Figure 1 is a sectional side elevation of the lock-plate of a door,showing a handle on the plate, and the preferable construction of theinvention as embodied within the handle; Fig. 2 is a side elevationexteriorly showing the same parts as seen in Fig. 1; Fig. 3 is a view toan enlarged scale, showmg the eccentrically arranged lever with which tooperate the latch-lever of locks of the several sizes. Fig. 4 is asectional view to an enlarged scale, taken on line X -'X of Fig. 1; Fig.5 is an enlarged fra mentary view of the knob-seat and the late i-boltof an ordinary lock; Fig. 6 is a view to an enlarged scale, of thelatch-handle and latcharm, taken on line XX of Fig. 1.

Like characters of reference designate like parts throughout the severalviews of the drawings. With particular reference to the draw- 1ngs-, thenumeral 10 designates an ordinary surface-plate or escutcheon, and 11 isa handle used in substitution for the ordinary knob with which to openor close the door or the like, on, in, or to which the handle isconnected. The handle 11 is held in place on the "outside of thesurface-plate 10, as by the integral bolt 12 which extends through saldsurface-plate and is engaged by a washer 13 and a nut 14 on the insideof the surface-plate. The circular spacing plate 15 is-located on thebolt 12 intermediate the hillltdle and the outer edge of the surfacep ae.

The handle 11 is hollowed out or recessed preferably as shown at 16, andtherein is located the latch lever 17 comprising the longarm orfinger-piece 18 and the short-arm or lever arm 19 which is fulcrumed inthe hollow portion 16 as at the bosses 20, by the pint-1e 21. Thelong-arm 18 near the fulcrum 21 is provided with a lug 22 projectingtoward the inner-wall 23 of. the recess 16, and on the inner-wall 23 isa similar lug 94, said lugs 22 and 24 being provided to respectivelyengage the ends of the spring 25. The finger-piece projects slightlywith out the recess 16 between the inner part of the handle and thesurface-plate 10.

vided for the purpose of permitting the end or knob 31 of the lever arm19, and the shortarm 32 of the bell crank 33 to operate therein in avertical plane. The bell crank 33 is fulcrumed between the lugs 30 as atthe bolt 34, and is provided with a long-arm 35, the same being thickerthan the short arm 32 and adapted to co-act with or actuate thelatch-lever 36 of a door lock as 37, whichv in turn operates thelatch-bolt of the door.

Particular attention is given the bell-crank 33, for it is desired toprovide the hole 34* eccentric to the common center thereof, so that itniay be used in locks of various sizes by simply inverting it. Theoperation of the invention is eX- tremely simple, and a briefdescription thereof follows :The bell-crank 33 is arranged and fulcrumedintermediate the lugs 30 as hereinbefore described, with the short-arm32 thereof projecting into the orifice 29, and is designed to engagewith the end 31 of the lever-arm 19 which contacts therewith on theupper part of said short-arm 32. The lever 1 being fulcrumed at 21 andheld normally as shown in Figs. 1 and 2, by the spring 25, and as thefinger-piece 18 is approximately three times the length of the lever-arm19, therefore the finger-piece 18 may be pressed into the recess 16 bysimply grasping the handle and as said finger-piece 18 is pressed intothehandle the end 31 bears downwardly on the bell-crank 33, therebycreating an upward movement of the latch-lever 36, which In turnoperates the latch-bolt of the lockby withdrawing the same from withinthe striking-plate not shown in the door sash, and when the finger-piece18 is again free, it will be quickly returned to its normal position bythe pressure of the spring 25. I I Obviously various changes may .bemade in the construction and organization of the parts and combinationof parts constituting the lHYGIltlOD, without departing from, orsacrificing any of the advantages thereof.

Having thus described my invention, I claim and desire to secure byLetters Pat-- entz- 1. A door handle or the like, comprising thesurface-plate having an eccentric bellcrank pivoted therein; a recessedhandle on the surface-plate, a latch-lever fulcrumed in the recess, withthe finger-piece projecting slightly therefrom; a spring in the recess-normally projecting sald finger-piece; and

an arm of said latch-lever in engagement with the bell-cranksubstantially as set forth.

2. A .door handle or-the like, comprising the surface-plate having aneccentric bellcrank pivoted therein; a recessed handle on thesurface-plate; a latch-lever comprising the lower-arm and thefinger-piece, fulcrumed in .the recess slightly .protruding'without saidrecess; and a spring in the recess in engagement with the finger piece;said leverarm being in contact with the inner arm of the bell-crank tomove the latch-lever of a lock when the finger-piece is moved inwardlyin gripping the handle, substantially as described.

3. In a door handle or the like the combination with a recessed handleand a surfaceplate; of a latch-lever comprising a leverarm and afinger-piece and being pivoted in said recess; an eccentric bell-crankpivoted within the surface-plate and having a shortarm projecting withinthe recess adapted to co-act with the lever-arm; and a spring in therecess in engagement with the fingerpicce to normally project the sameslightly without the recess and intermediate the han- I dle andsurface-plate as set forth.

4. In a door handle or the like, the combination with a su'rfaceplate;of a handle fastened on the surface-plate; a recess in the handle; alatch-lever.comprising a fingerpiece and a lever-arm, and fulcrumed inthe recess; an eccentric bell-crank pivotally fulcrumed in thesurface-plate, and contacting with the lever-arm of the latclrlever; anda spring in the recess in engagement with the finger-piece, to restoreit to normal position when released'from pressure with the fingers,substantially as described.

5. In a door handle or the like, the combi-v nation with a handle havinga recess thereln of a latch-lever comprising a lever-arm and a.finger-piece, and pivoted in the recess; a knob on the end of thelever-arm; a surfaceplate on which the handle is fastened a bell crankeccentrically mounted in the surfaceplate, partially projecting withinthe recess, and adapted to co-act with the lever-arm knob; and a springin the recess in engage ment with the finger-piece to normally projectthe same without the recess, and between the handle and thesurface-plate substantially as and for the purpose described.

.In testimony whereof, I have signed my name to this specification inthe presence of two subscribing witnesses. I
